Sažetak
Ozone (O3) is a secondary gaseous pollutant in the urban environment, and its variation correlates well with nitrogen oxides (NOx = NO + NO2). Continuous monitoring has been done in the Campo Grande city urban area, using ozone 49C and NO-NO2-NOx 42CTL gas analyzers. The results show that the maximum concentrations of O3 and oxidant (Ox = O3 + NO2) in Campo Grande often appear in the early afternoon around 15:00 hours. The daily variation of NO concentrations shows a very clear cycle with two peaks, one appearing around 07:00 a.m. and the other at 11:00 p.m. At the lowest level, NO2 is the main component of NOx, while NO dominates the higher mixing ratio. It is also shown that the level of Ox is composed of two factors: the regional and the local contributions. The former is affected by the regional O3 level, while the latter is effectively correlated with the primary pollution level. The daily variation also appears in the concentrations of oxidant components.
